Question

我有简单的django项目名称 Ajax 。我只为此项目名称 Promocode 安装了一个应用程序。我在这个项目中的问题是js和python之间的Ajax调用。我无法使用ajax调用函数处理 Succes 。错误：我得到的function（）结果。我知道我错误地在promocode应用程序中的urls.py和ajax调用函数中的url映射但我无法解决这个问题。请帮帮我:)。

我的主要urls.py文件是：

from datetime import datetime
from django.conf.urls import url,include
import django.contrib.auth.views

urlpatterns = [
   url(r'^', include('promocode.urls'))]

我的promocode app urls.py文件是：

from django.conf.urls import url, include
from . import views

urlpatterns = [
       url(r'^$', views.index,name='index'),
       url(r'^$', views.extract_json)]

我的views.py文件是：

from django.shortcuts import render
import json
from suds.client import Client as Client
from django.http.response import HttpResponse


def index(request):
    return render(request,'promocode/index.html')


def get_result_by_code(promocode):
    url = "http://service.emobile.az:8080/ws-loyalty-
    program/cp/loyaltyprogram.wsdl"
    client = Client(url)
    result = client.service.loyaltyProgramCalculate(
         amount=1000,
         authKey='testaede35740f2b9d2248b0ab6b878',
         identicalCode=promocode,
         terminalCode=2148)
    if str(result[2]) == "SUCCESS":
        status = 1
    else:
        status = 0
    return status


def extract_json(request):
    data = json.loads(request.body)
    status = get_result_by_code(data['4545'])
    result = dict(
       status=status,
       message='Result Succesfully'
    )
    return HttpResponse(json.dumps(result), mimetype='application/json')

我的index.html文件是：

<!DOCTYPE html>
<html>
<head>
<script 
src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js">
</script>
